There are loads of resources for making money online as an affiliate. You could source products from ClickBank, Commission Junction, Rakuten Marketing, Share-a-Sale, Impact Radius and many others. Plus, many of the larger companies have their own affiliate programs as well. Do your due diligence and find the right company with a relevant product or service to your audience that you can sell as an affiliate.
Mistake #2: Using the “They must not be my people” excuse to be spammy. I’m not a fan of this common tactic. Here’s how it works: people send a huge number of sales/promotional emails to their list with no warning and with no easy way to opt out. When people complain or unsubscribe, they put it on them (“Oh well, they aren’t my type of subscriber anyway…”), instead of taking responsibility for the spam (let’s call it what it is). What ever happened to “treat others the way you want to be treated”?
Next, you’ll want to pick a WordPress theme from somewhere like ThemeForest, Elegant Themes or OptimizePress. This is the barebones design of your site, which you can then customize with your own branding, copy, and images. That being said, you don’t want to cheap out. It costs less than $100 to buy a theme that will make your website look professional (and you can upgrade to a completely custom design once you get the business going).
